During my previous life in GMC world, Mobil 1 (oil, grease, and ATF) seemed to have been a favorite on this forum, such as it was.
I am getting ready to install my Ragusa tranny pan, and am wondering where Mobil 1 stands with this group. I still use Mobil 1 oil so that is not my question. Thanks.

I use Mobil one where ever I can. The ATF is expensive in the auto parts stores. They no longer carry it at Walmart however Walmart has another name brand of synthetic in 4 gallon containers that I was considering using when I replace the trans soon as the cost is a lot better. I don't think trans fluid is as critical as motor oil as far as brands is concerned.

I have a Manny Switch Pitch and he only uses Mobil 1 in SPs because of the extra heat that could build when in switch. It is $10 a quart which makes you wonder if there are flakes of gold in it.

Larry,
Mr. Transmission, Manny Trovao, says that Mobil 1 Synthetic Transmission Fluid is the best fluid available; however, it is not
necessary unless your GMC has a switch pitch transmission.
When you install our new Ragusa pan I would suggest using Permatex Aviation Gasket sealer on both sides of the gasket as that's what
Manny uses.
Regards,
Rob M.

I think Matt said Dexron is done at 305. Wondering what Mobil1 is done at and if worth the money as oppose to more frequent drain /fill with conventional. Also isn't all Dexron technically synthetic???

George B. wrote on Fri, 01 May 2015 09:34My coach has a trans temp gauge and you would be surprised at how quickly a trans heats up when you climb a hill even when not towing. Upon seeing the charts here elsewhere, showing how quickly the ATF deteriorates with heat, I was quick to install a trans cooler and really do not have to worry as much about the heat build up anymore. If your coach does not have a trans cooler synthetic ATF is a must if you encounter uphill grades and/or tow.
WARNING! Do not install a transmission temperature gauge; they cause a huge amount of driver stress!
And that is on my list of things to do, alongside Amsoil ATF. I'm sure the trans temp will go up a bit on the climb to Mt Charlston this summer.
Btw George, I may need a hand figuring out my low RPM stumble and it's still running pretty sluggish.
